A T TOR/VE YS Patented ct. 17, 1950 BUsnINeFoRwAGoNs .1 'I Ross W..P`helps, Orillia;Ontario, Ganada Application February 2, 1954-8, Serialo.'V 5587-5 1 This invention relates to a bearing--fandicnore particularly to a bearing suited for front or turning wheels of farm wagons and like applications, Aand a mounting therefor.

'It is an object of this invention to yprovidega bearing construction for use in farm wagons and like applications which can be quickly and easily assembled and disassembled.

It is a further object of this invention to provide a bearing construction in which the bearings can be easily and cheaply replaced.

It is a still further object of this invention to provide a bearing which is easy to lubricate.

With these and other objects in view the invention generally comprises a bearing including a grease tube with removably mountable bushings adapted to be retained adjacent the upper and lower ends thereof. The bushings are adapted to journal a spindle having a load plate secured thereto. The grease tube is mounted in a member to be supported by the load plate such as the bolster of a wagon, so that the load plate supports the bolster and the spindle is journaled within the bushings. The invention will be clearly understood after reference to the following detailed specification read in conjunction with the drawings.

In the drawings:

Figure 1 is a partial View of a wagon showing a portion of a bolster, a wheel and wheel l mounting mounted in the bolster according to the invention. The view is partly in section to show construction.

Figure 2 is an enlarged section taken along lines 2 2 of Figure 1.

In the drawings the letter A generally designates the wheel unit of a farm wagon and comprise an L-shaped member I0, the arm II of which is adapted to serve as an axle for a wagon wheel I2, and the arm I3 of which is adapted to serve as a spindle designed to be mounted for axial rotation within the bearing B in a front wagon bolster I4. A load plate I5 rigidly secured to the spindle I3 by any suitable means such as welding forms a support for the bolster. Means for controlling the axial movement of the spindle I 3 and the wheel unit A in the bearing B can be connected to the load plate I5. Such control means are well known and since they do not form part of the present invention are not shown in the drawings.

The wagon bolster I4 comprises a beam having a channel-like cross section. According to the embodiment of the invention shown a bottom plate I1 extends over at least part of the 8 Claims. (Cl. 3381-1-214.1;)v

In the embodiment of the invention shown the bushings I9 and 20 areformed with external shoulders 2| and 22 which are adapted y.to overf lie the-marginal edges of the grease tube I8. The bottom plate I'I encases the outer edge of the shoulder 22 of bushing 20 and an annular plate 23, secured to the upper side of the bottom plate II and extending to the grease tube I8, abuts the surface 24 of the bushing 2li. The annular plate 23 is secured `to the bottom plate Il by welding.

or anyfother suitable means.'

To assemble a wheel unit in thebearing described it is merely necessary to insert the spindle I3 into the bushings I9 and 2|] to cause the load.

suitable means such as a ring 26 which can be sprung to engage in a. groove formed in a projecting portion 21 of the spindle I3. The groove and spring ring construction is well known and is not shown in the drawings. The bolster I4 and grease tube I8 are formed with alignedopenings as at 28 and 29 for they A as a Whole is free to turn within the bearingB.'

From the above it will be apparent that yI have provided a bearing for wagon and'similar applications which accomplishes the objects of rthe invention.

The bearing can be quickly assembled and disassembled. To assemblel the unit it is merely necessary to place the bushings I9y and 20 in positiongwithin the grease tube I8, insert the spindle, and slip the ring 26 on the projecting end thereof. The reverse procedure to disassemble the bearing is equally simple. Thebushiylgg f 'I are very cheap to manufacture, easy t 'replace and easy to lubricate.

What I claim as my invention is:

1. A bearing for a spindle having a load plate rigidly secured thereto comprising a bolster, a grease tube, said bolster being bored to receive said grease tube, bushings mounted within said grease tube at its free ends, such bushings having bores that align when they are mounted in the free ends of said grease tube to rotatably receive said spindle, said bolster overlying said load plate.

2. A bearing as claimed in claim 1 in which said bolster and grease tube are formed with a grease opening into said tube.

3. A bearing for a, spindle as claimed in claim 1 in which each of said bushings are formed with an external shoulder that overlies the end of said grease tube in which it is mounted.

4. A bearing for a spindle having a load plate rigidly secured thereto comprising a bolster formed from channel cross section and a bolster plate closing at least a portion of the open side of said channel, a grease tube, said channel section and bolster plate being formed with aligned bores to receive said grease tube, bushings mounted within said grease tube at its free ends, said 4 bushings having bores that align when they ar mounted as aforesaid to receive said spindle, Said bolster overlying said load plate.

5. A bearing for a spindle having a, load plate as claimed in claim 4 in which each of said bushings are formed with a grease opening into said tube.

6. A bearing as claimed in claim 5 in which said bolster and grease tube are formed with a grease opening into said tube. v

'7. A bearing as claimed in claim l in which a Washer ts over said spindle and lies between said bolster and said load plate.

8. A bearing as claimed in claim 4 in which a Washer fits over said spindle and lies between said bolster and said load plate.
